farmer maggot to the hobbits sounds like something he would say jokingly while theyre reacalling old times "you used to pick around my mushrooms frodo
but now that im retired..." but he wasnt arrogant....(i like guessing hobbits huh?)
i know thats not the exact quote but its close
Grima to the three hunters right before he leaves for orthanc...hes arragant he was replaced as advisors (sort of) andhe would be one to claim that he left on his own accord vs being sent away.
again both wrong
but theyre my newest guesses
